The world is touched by sacrifice. It does not then discriminate about the merits of a cause. No so God - He is all seeing. He insists on the purity of the cause and on adequate sacrifice thereof.
One may say with one's lips: “I believe that the world was created six thousand years ago;” or, “I believe that Jesus flew away into the skies and is sitting on the right hand of the Father;” or, “God is One, and also Three;” — but no one can believe it, because the words have no sense.
A multitude of aspects of the natural world that were considered miraculous only a few generations ago are now thoroughly understood in terms of physics and chemistry.
